Ear Protection

Hearing protection helps reduce the amount of occupational noise reaching the wearer’s ears and supports a workplace hearing-conservation programme. Excessive noise can cause permanent hearing loss and may interfere with communication, warning signals, and concentration. Protective performance is expressed through attenuation values determined by standardised testing, but real-world performance depends on correct selection, fit, condition, consistent use, and the characteristics of the noise. The highest nominal attenuation is not automatically the best choice if the product is uncomfortable or prevents workers from hearing essential safety information.

Applications include manufacturing, fabrication, construction, utilities, compressor rooms, power generation, transport operations, and other environments where noise measurements indicate a risk. Selection should follow a noise assessment that considers sound pressure levels, frequency, duration, peak noise, task requirements, and the need to hear alarms or communicate. Where noise levels are especially high or exposures are complex, a competent occupational safety professional should determine whether combined protection or additional controls are required.
